What on EARTH are these??? #1
Hello All

Heres a couple of foto's of visitors i have in my tank, I can only get a foto of them "rear on" whilst stuck to the glass, as when not stuck to the glass they fly around the tank in the current, and under their own steam.

side on, they look like a shuttlecock, they are around 3 - 6mm long, and swim by convulsing. My guess is a jellyfish, based purely on how they move, but that really is a guess.

Any help greatly appreciated.
Cheers
Johnny-Boy

I remember EagleC has load of them on his tank and I think they're glass anemone which are bad un. they are aiptasia which are difficult to control as they multiply everywhere.

An alternative is Claudonema jellyfish, google it and have a look, they look, and by the description behave, very much as stated. hmmmmmmmm, will look some more......

Re: What on EARTH are these??? #5
yup thats what I have. Pretty sure they're not glass anenome. They dont look like any of the pictures I've seen of aptasia and they act like it either. I hadn't noticed the ones on the glass where the same as the tiny jellyfish I very occasionally see.

Going to do some googling on these Claudonema jellyfish now.


//edit// yup that set me on the right track. I believe they're Hydroid Jellyfish or Staurocladia oahuensis (mine are at least, yours are a little bigger.)

Re: What on EARTH are these??? #6
You both could be right it claudonema jellyfish, glass anemone look familiar when they are tiny and then settle down on LR and are aiptasia species. Nice to see you have jellyfish.

Re: What on EARTH are these??? #7
I have bad memories of hydroid jellyfish from diving on holiday. Keep a bottle of vinegar handy for the stings
